WRENCH.

' Application filed April 15, 1926. Serial No. 102,255.

This invention relates to improvementsin wrenches, and the object oi theinvention is to provide a wrench that can be instantlyv` changed to fitany sized nut, whereby when I used by mechanics and others moreVsatisfactory and quicker results are obtained than' wrench with thefiller blades mostly in in my invention is illustrated, 10 designatesyan ordinary wrench as a whole, provided with 'recesses' 11 and 12 ofdifferent dimensions at each end, the ends as is well `known beingenlarged as at 13 and 14, and the intermediate body portion 15 formingvthe handle portion for the wrench. n

Adjacent the recesses 11 and 12 and in the body portion are slots 16 and17 spaced from said recesses by solid intervening portions 18 and 19.

Within these slots, pivotally mounted on pins 20. are a plurality ofliller blades 21, adapted in inoperative position to lie snugly withinthe slots and, as illustratedin 1,'Husli with the surface oi' the bodyportion. These filler blades are provided with recesses or cutouts 22designed to engage with the shoulder or bridge portions 18 and 19entrated in Fig. 1, in the recesses 11 and 12 to automatically curtailtheir size and there- .structed without departing from the spirit`wrench.

abling the blades to iit snugly, as also illusby adapting them to fitbolt nuts of different sizes. According to the size of the nut, one

or more of the blades `21 may be employed. 55 For swinging the bladesinto operative position I provide thumbnail spaces yor recesses 23 inthe sides of the wrench. The

outer ends 24 of the blades are preferablyr slanted to engage with theslanting ends 25 `60 of the recesses 16 and 17 in inoperative positionand thus limit the travel of the blades beyond a predetermined point.

From the foregoingy the operation of my wrench will be apparent, as inorder to ad- 65 )ust it to fit anysize of nut it is onlypnecessary toswing as many of the blades 21 as may be necessaryto form a clampingmeans roi* the nutfrom their inoperative position into kone of the endrecesses v11 'and 12.

As many changes could be made in the Yabove construction and 4manyapparently widely .dili'erent embodiments of my inven-4 tion, within thescope of the claims, conor scope thereof, it is intended'that all matpter contained in tlie'present specification and laccompanying drawingsshall be interpreted in an illustrative and not in a limiting sense.

lVhat I claim as my invention is: 1. A wrench comprising a body portionrecessed at one end, intermediately rand centrally slotted, a pluralityof liller blades pivotallyk mounted in said` body adjacent to the recessand formed on the under side with recesses to engage with the body, saidblades being adapted tobe moved selectively and` collectively ,to renderthe wrench adjustable and to fit flush with the surface of the 2. Thecombination with a slotted wrench or spanner provided with enlargedportions ateacli end, one of said enlarged portions being partially cutout or recessed, a plu rality'of blades formed on the under side withrecesses pivotally mounted in said slot and adapted to swing across andengage with the recessed enlarged portion to adjust the size of thewrench and to swing in the 0pposite direction flush with the surfaceofthe wrench.

In witness whereof I Ahave hereunto set my hand. I
